Fortress 12KW | 16KWH Storage | 12KW Array | Tigo Rapid Shutdown | Kit

Fortress 12 kW Solar + Storage Kit Summary

System: 12 kW PV Array | 16 kWh Storage | 12 kW Fortress Inverter | Tigo Rapid Shutdown

The Fortress 12 kW Solar + Storage Kit is a turnkey photovoltaic and energy storage solution designed for residential and light commercial properties. This integrated system delivers reliable daytime solar generation, robust energy storage capacity, and necessary safety features for modern grid-connected installations.

Core Components

• 12 kW PV Array
  A DC photovoltaic array sized at 12 kW for substantial on-site power generation. This capacity supports significant daytime consumption, battery charging, and reduced utility dependence.

• 12 kW Fortress Inverter
  The kit includes a 12 kW Fortress inverter, which serves as the central power conversion unit. It converts DC power from the solar array and battery into AC power for loads and grid export (if configured). The inverter also manages charging/discharging of the battery and coordinates system operation for resiliency, efficiency, and compliance.

• 16 kWh Battery Storage
  A lithium-based energy storage bank with 16 kWh usable capacity. This storage enables load shifting, peak shaving, and extended backup capability during utility outages. It is sized to support essential loads through periods of low or no solar production.

• Tigo Rapid Shutdown System
  Included or supported Tigo rapid shutdown hardware provides module-level shutdown control. This enhances safety for first responders and maintenance personnel and ensures compliance with NEC rapid shutdown requirements.

Benefits & Performance

• Enhanced Energy Resilience
  The integrated storage supports sustained operation during grid outages, enabling critical load support and energy autonomy.

• High Solar Yield
  A 12 kW PV array produces significant midday energy, which can be consumed onsite or stored for later use.

• Reliable Power Conversion
  The 12 kW Fortress inverter balances solar generation, storage charge control, and load demands. It supports grid synchronization, battery management functions, and optimized energy dispatch.

• Improved Safety & Code Compliance
  Tigo rapid shutdown brings module-level de-energization capability to meet NEC safety standards. This reduces the risk of high-voltage DC on roof circuits during maintenance or emergency response.

Typical Applications

• Residential solar installations seeking substantial self-consumption and backup capability.

• Light commercial sites where midday generation and resiliency are priorities.

• Retrofit projects requiring enhanced safety (rapid shutdown) and storage integration.

Design & Installation Considerations

• Proper string sizing and inverter configuration are essential to maximize performance and comply with electrical codes.

• Communication and monitoring setup (e.g., Wi-Fi dongle connectivity) should be verified during commissioning.

• Coordination with local utility for interconnection and any net metering arrangements is required.
